CAPE SPENCER against its type
It is one of 307 container ships here under the Portugal flag, 8.8% of the 3,495 on the register.
Its 10,208 t of CO₂ for 2025 is 38% below the median of 16,359 t among the 2,234 container ships on this register that reported for 2025. Per nautical mile it emitted 345.6 kg CO₂, 37% below the type median of 545.6 kg. It logged 2,092 hours at sea against a median of 3,155 hours for its type that year. 4.3% of its 2025 emissions were at berth; the median for container ships was 3.2%. Across 3 years with reported emissions, the highest was 2025 (10,208 t) and the lowest 2023 (3,039 t). Its efficiency percentile within the type went from 83 in 2024 to 76 in 2025 (lower is more efficient). Of the 8 comparable vessels listed below with a 2025 return, 4 reported a lower CO₂ per nautical mile than this vessel.

Efficiency against its own type2025
Position 1,395 of 1,838 qualifying container ships by EEOI, at the 76th percentile. The dashed line is the type median, 14.2; this vessel reported 23.2.
EEOI divides emissions by transport work, which for this vessel and year was 439,807,841 tonne-miles over 29,533 nautical miles.
Reported CO₂ by year
Reported CO₂ in 2025 was 235.9% higher than in 2023, for EU/EEA voyages only.
From 2024 to 2025, emissions rose 7.0% while distance sailed fell 7.5%and CO₂ per nautical mile rose 15.8%.That points mainly to how efficiently it sailed, rather than the other.
